I have been using these kneepads for about 6 months and I have not yet regretted buying these.
These kneepads are very comfortable. They are a little tight when you first put them on but after breaking them in a bit, they feel amazing. You start to forget you have them on throughout the day, when you are playing.
They protect very well, and I'm happy to be using these, rather than sliding with bare knees. They are cushioned and you hardly feel anything when you are sliding into your bunker. My knee's have been saved countless times using these.

EDIT: These pads have been working my nerves lately. They protect well, but EVERY time I slide on my knees, they fall down, which forces me to stop and pull them up mid game. I can't slide or dive anywhere with out them moving. It's really annoying, and effecting my playing.

Conclusion:

These are awesome kneepads. I reccommend these to anyone looking for high quality pads for a relatively decent price. Definitely consider these when shopping for pads.
